Summary:                    Asterisk fails to recognize SUBSCRIBE
retransmissions and tries to re-authenticate them, which breaks presence on
polycom phones
Description: 
Here's what happens from asterisk point of view:
-> SUBSCRIBE
<- 401 Unauthorized
-> SUBSCRIBE with auth
<- 200 OK (lost)
<- NOTIFY
-> 200 OK for NOTIFY
-> SUBSCRIBE with auth retransmission
<- 401 Unauthorized
At this point polycom phone received 2 "401 Unauthorized" in a row and it
completely gives up on resubscribing to this hint until reboot. While
polycom behavior is questionable, I believe asterisk should recognize
retransmission and resubmit 200OK in this case
